LibreWolf 155.0.1-1

LibreWolf: A Privacy-First Firefox Fork for Secure Browsing

LibreWolf is an open-source browser derived from Mozilla Firefox and configured to reduce telemetry, tracking and fingerprinting by default. It delivers a privacy-focused experience through hardened preferences, curated patches and community-maintained builds across Linux, Windows and macOS while retaining compatibility with mainstream web standards.

What LibreWolf Changes Compared to Firefox

• Telemetry and data collection removed: Mozilla telemetry, studies and other data-collection features are disabled or stripped to minimize outbound data.
• Hardened privacy defaults: Settings are tuned to block third-party trackers, resist fingerprinting techniques and tighten cookie handling for stronger privacy without manual configuration.
• Reduced background services: Built-in services tied to telemetry and data collection are removed to limit network calls and potential privacy exposures.
• Custom builds and distribution: Official and community builds are provided as distribution packages, Flatpak, and in the Microsoft Store; update delivery is handled through OS package channels or store updates rather than Firefox’s native updater.

Performance and Compatibility

With tracker and ad blocking enabled by default, LibreWolf often yields faster page loads and lower resource use compared with an unmodified Firefox profile. Extension compatibility is preserved, allowing installation of popular add-ons such as content blockers and other privacy-focused extensions while keeping the project’s stricter defaults.

Security Features and Updates

• Community-maintained security patches: Community contributors backport security fixes and maintain privacy-oriented patches for official builds.
• Stricter security settings: Defaults governing cookies, referrers and mixed content are set to reduce attack surface without additional user configuration.
• Update practices: The browser disables Firefox’s automatic telemetry-driven update mechanism; updates are intended to be applied via LibreWolf distribution channels, Flatpak, repository packages or the Microsoft Store.

Usability and Customization

The user interface and customization model of Firefox are retained, including themes, toolbar adjustments and accessibility features such as font scaling and screen reader support. Privacy-focused defaults are applied without removing standard customization options, making LibreWolf suitable for everyday browsing as well as privacy-centered workflows.

Target Users

• Privacy-conscious users: Suitable for those who want reduced telemetry and stronger tracking protections while remaining within the Firefox ecosystem.
• Open-source advocates: Appeals to users who prefer transparent, community-driven builds and curated source changes.
• Power users: For users who prefer granular control over browser behavior and managing updates through package managers or app stores.

Availability and Installation

LibreWolf publishes platform-specific packages and installation instructions on the project website and offers distribution options including official release archives, Flatpak, Linux repositories and a Microsoft Store listing for Windows. These channels provide the primary paths for installation and receiving updates.
